History

The Don was designed to meet Air Ministry Specification T.6/26 for a multi-role trainer and was a single-engined monoplane of wooden stressed-skin construction. The Don was intended to be a trainer for pilots, radio operators and as a gunnery trainer. The gunnery requirement involved the mounting of a dorsal gun turret. This is a partial list of the British Air Ministry specifications for aircraft. ...

The prototype (Serial Number L2387) first flew on 18 June 1937 and was transferred to RAF Martlesham Heath for trials. As a result of the trials the aircraft had to be modified which increased the weight. The dorsal turret was removed in an attempt to reduce weight, but the aircraft was not suitable for training. The original order was for 250 aircraft but in the end only 50 aircraft were completed, 20 were delivered as engineless airframes for ground training. The remaining aircraft served as communications and liaison aircraft. June 18 is the 169th day of the year in the Gregorian Calendar (170th in leap years), with 196 days remaining. ...

In aviation, the Maximum Take-Off Weight (or MTOW) is the maximum weight with which an aircraft is allowed to try to achieve flight. ... VNO of an aircraft is the V speed which refers to the velocity of normal operation. ... The maximal total range is the distance an aircraft can fly between takeoff and landing as limited by its fuel capacity. ...
